Heat Treat Furnace Cart

I needed a cart for my two heat treat furnaces. I can use one furnace immedeatly because it only pulls approximately 15 amps of single phase 220v and the other I am saving for a day I have access to three phase power. It's a 12.2kw beast of a furnace that weighs approximatley 850 lbs.

I first designed the frame on solidworks and I had a local shop sell me shear cut peices of 12 gauge steel for the tops and bottom.
